Standard pump motors have open drip proof construction and are rated with jet pump service factors for continuous duty operation at all ratings shown. Single phase motors are capacitor start/induction run with buitin overload protection. Three phase motors require a magnetic type starter which provides full 3-leg overload protection. Failure to use the correct starter and overloads will void the warranty.

For Temperature to 500°F (260°C) - Series CS Pumps are available in a Jacketed Seal Cavity design for pumping hot oil, hot water and heat transfer fluids in common use in high temperature heating or cooling applications. This feature greatly extends seal life in high temperature applications. To order, add suffix “J” to pump catalog number for temperatures below 400°F (204°C) and add suffix “JK” to pump catalog number for temperatures over 400°F (204°C). Example: 15CS5MJ.
